some brands of coke machines have had surge pricing ability for at least 30 years. I was told it was usually used to raise prices in between class periods in school machines but none of the ones I ever programmed used the feature just flat rates.
Some day all people with shower with electric heaters connected directly to solar panels. For now, we can only pity them (my energy come from hydro I guess, so it’s water being heated by otther water))
Amazing they didn’t do that earlier. In Rio de Janeiro there’s a vegetables store chain that use that since years ago.
